SUPPLEMENTAL HORSESHOAE.

SPECIFICATION forming part of Letters Patent No. 229,607, dated July 6, 1880. Application filed February 3, 1880.

To all whom it may concern:

Be it known that I, CHAS. G. HILL, of Arlington, Baltimore county, State of Maryland, have invented certain new and useful Improvements in Supplemental Horseshoes and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being bad to the accompanying drawings, in which- Figure l is a bottom plan of the device; Fig. 2, a central longitudinal sectional view of the same.

My invention has reference to that class of horseshoes designed to be removably attached to the permanent shoes; and it consists in a supplemental shoe whose pivoted arms are attached to the toe-piece and are adapted to be expanded so as to clamp the device to the permanent shoe, as hereinafter set forth.

In the accompanying drawings, A is the front or toe piece, provided with a flange, a, which enters between the permanent shoe and the hoof. Screws a a are inserted from above through the piece A and subserve the ends of calks.

Arms B B are pivoted at b b to the piece A and carry at their rear ends the heel-pieces E, which have screws to and flanges similar to those of the toe-piece A, and for a similar purpose.

From the rear side of the piece A projects a screw, (3, which passes through a cross-bar, D, having at its ends jaws d d, thatengage with and slide upon the arms B. A nut, c, servesto drive the cross-bar D forward toward the toe-piece.

In operation the nut is turned back sufficiently far to enable the device to be inserted within the permanent shoe, the flanges of the toe-piece Aand heel-pieces E coming between the shoe and hoof. The nut c is then screwed up, driving before it the bar D and expanding the arms B B, whereby the device is securely clamped to the shoe.

Instead of having the flange a on the toepiece A, the ends of the arms B may be provided with flanges, which will subserve the same end. The screws to may be readily removed when worn out, and are by preference constructed of mild steel, combining the attributes of strength, toughness, and hardness.

Instead of providing the toe and heel pieces with removable calks, their outer edges may be bent up at right angles to the plane of the shoe, subserving the same end.

What I claim is- 1. In combination with the calked toepiece and arms B, pivoted thereto and having terminal calks, the rod 0, secured to the toe-piece, and transverse rod D, as set forth.

2. In combination with the toe-piece A, having flange a, the arms B, having similarlyflanged heel-pieces E, and the rods 0 and D, as described.

3. In combination with the toe piece A, arms B, and heel-pieces E, the rod 0, nut c, and transverse bar D, having terminal jaws d, as described.

CHARLES G. HILL.
